To all whom it may concern.-

Be it known that we, AXEL F. BACKLIN and IDoFF EKLUND, citizens of theUnited States, residing at WVorcester, county of Worcester, State ofMassachusetts, have invented certain new and useful Improvements inDriving Mechanism for Coiler-Spindles of Wire-Fence Machines and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates to driving mechanism for thecoiler-spindlesof'wire-fence machines of the general type shown in thepatents to A. J. Bates, No. 577,639, granted February 23, 1897, and No.591,996, granted October 19, 1897, and has for its object to improve andsimplify the means for rotating the coiler-spindles therein byconnecting the latter with positively-driven gearing that is operatedfrom a shaft rotated intermittently fore constructed motion is impartedto the driving-spindles by means of a reciprocating rack, which iscaused to engage and disengage the coiling-spindles at proper intervals.This form of transmission has proven somewhat troublesome andunsatisfactory, as it is liable to excessive wear and breakage and alsoabsorbs a considerable amount of power during the period of itsoperation when it is not actually doing the work of driving thespindles. By means of the present invention this old form of racktransmission is dispensed with, and the gears by means of which thespindles are rotated are constantly in mesh, have no reverse motion, andare driven only during the period of actual operation of the spindles.

In the accompanying drawings, Figure 1 is a fragmentary section throughthe front part of a wire-fence machine of the type hereinbefore referredto, showing the improved driving mechanism applied to thecoiler-spindles. Fig. 2 is a side elevation of a section of the machine,showing portions of the spindledrive in section. Fig. 3 is a horizontalplan view on the line 3 3 of Fig. 2. Fig. 4 is a plan view of thespindle end of the machine, showing the mechanism for intermittentlyactuating the main shaft of the driving mechanism In the machines ashereto-' for the coiler-spindles. line 5 5 of Fig. 4.

In all of the figures of the drawings only suflicient of the mechanismof the wire-fence machine is shown to properly illustrate the inventionand indicate its relative arrangeifient and cooperation with thecoiler-spin- Referring to the drawings, 0!. indicates the machine-frame,in which is mounted the vertical shaft 1), which is divided into twoportions united by a suitable coupling d, the up per member projectingthrough the top plate of the machine and being provided with abevel-pinion e for imparting intermittent rotatory motion to said shaftby means of a crank-and-ratchet mechanism, to be more particularlydescribed hereinafter, so that while the main shaft of the machine isdriven constantly in one direction an intermittent rotatory motion isimparted to the coilerspindle-driving shaft I). Said shaft finds itslower bearing in a'suitable bracket f on the machine-frame and passesthrough a series of double brackets f, also connected to themachine-frame, which double brackets are provided with readily-removablecap-plates m. Between the double brackets aforesaid there are mountedupon the machine-frame single brackets, one of which, f is shown inFigs. 1 and 2. Mounted in suitable journal-boxes in the brackets f and fso as to lie parallel with the shaft 1), are a series of stub-shafts i,corresponding in number to the coiler-spindles Z. The lower ends ofthese shafts are provided with pinions h, which mesh with s ur-gears g,secured to the shaft 6, and upon t e upper end of each of thestub-shafts i there is secured a bevel-gear j, which meshes with abevel-pinion is on the end of the corresponding coiler-spindle. Thestub-shafts 't are so located as to leave a free passsage-way below theends of the same to permit the strand-wires to pass freely through thehollow coiler-spindles Z, as will be evident from an inspection of Figs.1 and 2.

Mounted on the top plates of the machineframe a is a short shaft g,having thereon a bevel-gear p, meshing with and serving to drive pinione and shaft 1). Fixed to said shaft 9 is a ratchet-wheel s, which isopera- Fig. 5 is a section on tively engaged by a pawl 8, said pawlbeing pivoted on the end of an arm 1', loosely j ournaled on shaft gadjacent to the ratchetwheel 8, said arm r being in turn connected,through an arm a: on a sleeeve w, loosely mounted on a shaft parallelwith said shaft q, to a crank-disk v on a counter-shaft a,which isdriven directly from the main shaft'of the machine.

The operation of the driving mechanism will be readily understood fromthe foregoing description to be as follows: As intermittent rotatorymotion is imparted to shaft 1) by means of gear h and thecrank-and-ratchet motion connected'to the main driving-shaft of themachine, gears g, meshing with pinions It, will rotate stub-shafts i,which through the meshing double gear j and pinion Zc rotate therespective coiler-spindles Z to twist the staywires and strand-wirestogether in forming the fence fabric. As soon as the rotation ofshaft 1) is interrupted, which operation takes place at the proper timeby the action of the crank and ratchet, the rotation of thecoilerspindles is of course suspended, and the transmission systemremains'idle until the next partial rotation of the shaft 6. By thismeans it will be seen that the coiler-spindles are positively driventhrough just the proper number of rotations by gearing that isconstantly in mesh and that during the idle period of thecoiler-spindles no motion Whatever is imparted to the transmissionsystem or any part thereof, so that the excessive wear and breakage dueto engaging and disengaging the driving mechanism and the loss of poweroccasioned by the retractile movement of the rack in the old form oftransmission is entirely obviated.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

Coiler-spindle-driving mechanism for wirefence mach mes, comprising avertical drivingshaft receiving an intermittent rotatory motion from themain shaft of the machine, a series ofcoiler-spindles, a series ofspur-gears on said driving-shaft corresponding in number to thecoiler-spindles, stub-shafts mounted upon the machine-frame adjacent tothe respective coiler spindles, a pinion and a bevel-gear on therespective ends of the stubshafts, and a bevel-pinion on each of thecoiler-spindles, the bevel-pinion on the respective coiler-spindlesmeshing with the corresponding bevel-gear on the stub-shafts, and thepinion on the respective stub-shafts meshing with the correspondingspur-gear on the driving-shaft.

In testimony whereof we affiX our signatures in presence of twowitnesses.
